Here is my humble first freebie, soon to be commissioned at the Renderosity freebie site. It's far from perfect. The hull was created from a set of offsets I found on the web, the rest was kinda put together from experience sailing, memories, dreams, wine... well, just a little of that. ;)

It's been a long time making.

No, it's not the Daz Sloop John B. I actually bought it recently, just to see what I needed to do differently, and I'll have to say that whoever modeled it did a great job. I'm not in this class of modeler at all - just a self-taught Blender wanna-be, learning it bit by bit, that's it. What an incredible tool Blender is, though, hey?

So, here she is, so far:

The hatch slides back and forth, the tiller moves the rudder and moves appropriately, the stern hatch opens and closes and the main/boom moves out ...

but here's where the issue has reared its ugly head: there's a conspicuous absence of mainsheet -  how do I make a mainsheet that will behave naturally? I suppose this might take a bit of modeling in Blender, and then creating morph targets from that in Poser, but does anyone have any experience with lengthening/shortening rope props?
In short, how do I allow the Poser artist to lengthen/shorten those lines just by moving the boom?

I've decided not to try to model sail shape variations based on topping lift/boom-vang settings. Too complicated, and I don't think it will add to the end-product enough.

Yes, this will be a freebie, once I get that issue sorted. I will deliver it sans interior. Perhaps I should make the interiors before I publish it?

What do you all think?
